    How long to start populating Prefetch folder?


    Because I got a new motherboard, I had to do a clean reinstall of Win 7 Pro 32-bit SP1 on June 9. Here it is June 21 and my Prefetch folder has zero program entries. In addition, possibly related, from the time I boot my PC until all the hard drive thrashing is finished is 2 min, 15 sec. Soluto said that a full 58-65 seconds of that was Avira Free loading and scanning at boot. It also takes a long time to launch any other programs, no matter what they are. Virus and malware scans are clean.

    I've done a site search for this. I checked the Registry for that key value that tells Windows to prefetch everything, and I do not use CCleaner to clean out old prefetch entries. I have checked the Prefetch folder for content at random times and there's never any new entries there, even days after booting and running (I run Folding@Home 24/7).

    What gives? Any ideas? I'd appreciate some insight.

    I have read many post on this form where people are having problems of all kinds using Avira.

    I recommend removing Avira using their on line method and installing this for a test.

    If you are using Ready Boost I recommend not using it and install more ram. Your motherboard is fully capable of up to 32 gigs with 4 ram slots. All ram should be matching ram.

    I've been considering moving back to Avast because of good performance reviews.
    AFAIK, ReadyBoost is used for external drives. I have none.
    How will installing more RAM help? I'm maxed out using Win7 32-bit.
    I've even wondered if I should revert to IDE mode and MS drivers for my hard drives instead of AMD AHCI drivers.
    I"m trying to figure out what I did wrong at some point, because I never had this trouble with my old ASRock board...

    Try setting BOTH EnablePrefetcher and EnableSuperfetch registry settings to 3. That's how MS sets them as default. I find my prefetch populates quite quickly. I often delete the program prefetch just for grins. The boot prefetch(which is in the readyboot subfolder) I don't bother to clear unless I made changes to the startup programs. You get one slow boot if you delete ReadyBoot contents. Then it's cached.

    I'll try that later.

    I've also done a bit more online research and I've discovered that there is no layout.ini file in my prefetch folder... or anywhere else on my computer, for that matter.

    Well I didn't notice that in your system specs (32) bit. Sorry about that. That just means it would be a good time to go to Windows 64 bit.

    Same problem with Troubleshoot Application Conflicts by Performing a Clean Startup ? Revert to normal boot after testing!

    Try this to rebuild the layout.ini prefetch file.

    a) Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow
    b) Type the following command, and then press ENTER:
    c) Rundll32.exe advapi32.dll,ProcessIdleTasks
    Note: This will rebuild the layout.ini file, even if it has been deleted from %windir%\Prefetch.

    I had run the ProcessIdleTasks thing automatically every four days via Task Scheduler and it never rebuilt layout.ini.

    But I did manage to fix it.

    Turns out that MilesAhead had the clue. I checked my Registry as he suggested, and all entries had a value of "3".

    Then I opened up Services. Superfetch was marked as "Manual" and "Stopped". I started the Superfetch service, changed startup to Automatic. Ran a few programs and immediately found them in Prefetch. I rebooted, ran ProcessIdleTasks, and voila: a normal Prefetch folder with a fresh layout.ini!

    I think I can mark this one solved, gents. Thanks for the help!
